Help With Recording Equipment (external soundcard/phantom power)

I just recently purchased a laptop switching from a desktop to make my equipment more mobile and durable.

I have been searching for a external soundcard and/or phantom power preamp to bypass the basic quality of the soundcard my laptop comes standard with. I am aware that a soundcard is hard to replace within a laptop due to its small space and it would be hard to put a desktop based soundcard into a laptop due to that. With that being said I am in need of suggestive help looking for somekind of external soundcard or preamp with phantom power that will still give me the similar quality that i've previously been capable of with the desktop.
